摘要:To be able to understand the interactions of human activities within the physical environment, it is pertinent to study the land use land cover of the area under investigation. This research therefore, focuses on change detection in Land use Land cover in Minna Nigeria. To analyze the change, Land sat ETM 1990, Landsat ETM 2000, Landsat ETM+ 2005 and Landsat ETM+ 2015 imagery covering the area between 1990 and 2015 were obtained. To interpret and verify the accuracy of the satellite imagery, ground truth observation was conducted on the land use and land cover of the study area. The research employed the use of supervised digital image classificatio n using Arc GIS 10.1 and ERDAS Imagine 9.0 software to classify the area into built -up, vegetatio n, farmland, water body and bare surface. Result obtained shows so me changes in land use land cover classes within the period (1990-2015); built-up area experienced rapid change with an increase o f 38.66 km2, and a decrease of -5.32 km2 in vegetation. Decreases were also observed in farmland, water body and bare surface with -1.95 km2, -0.05 km2 and -32.78 km2 respectively. It is therefore, recommend ed that regional development planning be encouraged to regulate growth in land use land cover for a sustainable urban development be achieved.
